Abstract:
Surface decontamination efficacy determination of DeconGel™ 1101 and 1102 on stainless steel, aluminum, and concrete surfaces contaminated with Jet Fuel using GC/MS (Gas Chromatography/Mass Spectrometry) following Environmental Protection Agency (EPA) SW-846 Methods: 3500C (sampling) and 8270C (analysis).

Hazardous Materials Relevance
Jet Fuel (Jet A) is a C8-C16 kerosene-type flammable fuel. Jet Fuel vapors and liquid are harmful, ingestion of sufficient quantities can be fatal, therefore, Jet Fuel use requires adopting safe and proper handling, storage, and disposal procedures.

Summary Results

  • As seen in Table 1, excellent surface decontamination was achieved by applying DeconGel 1101 and 1102 both via brushing or pouring (non-brushed) onto contaminated surfaces, resulting in encapsulation of Jet Fuel contaminant by DeconGel's active components. Decontamination efficacies of poured DeconGel 1101 ranged from 90.3% (on concrete) to 94.4% (on stainless steel) to 94.5% (on aluminum), brushed DeconGel 1101 ranged from 98.7% (on concrete) to 99.2% (on stainless steel) to 99.4% (on aluminum), as determined by residual swipe analysis. Decontamination efficacies of poured DeconGel 1102 ranged from 89.2% (on concrete) to 92.7% (on stainless steel) to 92.9% (on aluminum), brushed DeconGel 1102 ranged from 98.9% (on concrete) to 99.4% (on stainless steel) to 99.4% (on aluminum), as determined by residual swipe analysis.
  • • Optimized experimental and analytical methods were successfully developed following standardized EPA sampling and analysis methods as guidelines for determination of organics in polar solvent solvated samples. When necessary, the digestion methods were customized to result in the complete dissolution of the organic contaminants and to ensure accurate decontamination efficacy determination of DeconGel.

Results:
Table 1 shows the decontamination efficacies of DeconGel 1101 on stainless steel, aluminum, and concrete surfaces contaminated with Jet Fuel as determined by residual swipe testing.
